The same clock source must be used for the prescaler operating clock and the CPU operating clock.Therefore, when operating the CPU in low-speed with the OSC1 clock, the prescaler input clock must be switched according to the CPU operating clock. In this case, in order to prevent a malfunction in the peripheral circuit, the prescaler should be turned off before switching the CPU operating clock. After the CPU operating clock has been switched, switch the prescaler operating clock and then turn the prescaler on.
